Challenges, risks and benefits for SMEs.
Harty, James; Kouider, Tahar; Paterson, Graham J.
The transition to a BIM collaborative working environment poses a number of challenges, risks
as well as benefits for small and medium enterprises in the constructions sector as whole. The
technology gap within the construction industry continues to widen between large companies
and SMEs / micro-SMEs. Amongst the former, Information and Communication Technology
(ICT) is pervasive and has become a key infrastructure covering all aspects of business
including design, construction, asset management, life cycle, marketing, cost management
etc. Amongst the latter however, ICT is often limited to traditional 2D drawings, perhaps some
static 3D visuals, email and possibly a symbolic internet presence. The status quo creates a
divide in the industry and potentially may lead to a Macro versus Micro effect that will certainly
hamper any effort for collaboration within the industry. The real challenge here, one would
argue, is for those large organisations with experience and expertise in BIM to match their
legitimate marketing discourse with a similar level of actions by providing reliable and credible
case studies and even collaborate with SMEs to raise industry level and help to achieve a
faster and smoother transition to BIM.

Analysis of collaborative design and decision making through argumentation applied for pre-BIM stages.
Leon, Marianthi; Toniolo, A.
The early design stages are the most vital for the development of the design of a building project and the decisions taken during these steps are significant for the further progress of the project, regarding aspects like cost, performance, reliability and sustainability. Being able to trace backwards the thoughts that led to these decisions at any point of the design process provides clarity and transparency during the decision making process. Additionally, monitoring the design steps and decisions can lead to further observations on the effects of the design decisions during the early design stage, thus leading to a more sustainable and holistic design approach. This paper claims that efficient monitoring of the decision steps can be achieved employing a computational model of argumentation. Argumentation-based reasoning helps identify the rationale for a decision (i.e. arguments) and the relationships (i.e. attacks and preferences) between conflicting issues involved in making decisions. Our approach provides a method to rigorously trace the resolution of conflicts by extracting the set of acceptable arguments that led to a decision, and may eventually assist designers in analysing complex collaborative decisions within a pre-Building Information Modelling context.

Making collaboration work: application of a conceptual design stages protocol for pre-BIM stages.
Leon, Marianthi; Laing, Richard Alexander; Malins, Julian Paul; Salman, Huda Shakir
This paper presents the application of a Conceptual Design Stages Protocol during feasibility stages within a multidisciplinary design team, for the purpose of bridging the gap between ideas generation and their representation in later and more advanced design stages. Increased effort during the early and conceptual design is a prerequisite for effective and sustainable overall design and construction. Consequently, shift of the effort towards feasibility stages aims to tackle problems with workflow, education and organisation of design teams at the very beginning of a project. Furthermore, the application of an organised process during conceptual design could further support a multi-party agreement, hence enhancing the potentials of collaboration and coordination for the entirety of a project. This paper demonstrates the Conceptual Design Stages Protocol as an organised process encompassing different professionals, technologies and means for communication that has been tested in a conceptual stage study and the outcomes have been incorporated within BIM. The impact of this Protocol on designers’ cognitive, physical, perceptual and collaborative actions is presented and the first pre-BIM Protocol is established.

Scan to BIM: the development of a clear workflow for the incorporation of point clouds within a BIM environment.
Laing, Richard Alexander; Leon, Marianthi; Isaacs, John; Georgiev, D.
The emergence in recent years of technology to support the use of data rich models within architecture has significantly aided the uptake of building information modelling. Simultaneously, there has been a rapid expansion in the capabilities and widespread use of 3D high definition laser scanning technology. Although laser scanning has often been associated with industries outside of architecture and building (including heavy engineering and oil and gas installations), the potential to record the existing built environment is clear. Indeed, well-established concepts within building and materials conservation concerning the importance of being able to accurately monitor and recognise the importance of surface characteristics are well suited to the use of scanning to capture geometrical idiosyncrasies as well as designed detail. Likewise, the ability to capture structures which are well outside the physical reach of the expert makes the accurate recording of large scale buildings and streetscapes possible, and at a speed and level of accuracy which was not feasible even 15 years ago. This paper concerns a series of workflow stages which are required to incorporate the output of laser scan data within a BIM environment. Although it is possible to import point clouds within industry standard BIM software, in order to make best use of the highly accurate and often massive data files a certain amount of post-processing and modelling is required. We describe a process whereby cloud data can be transformed to produce representative surface meshes, and explore how the resultant models can be linked with meta data within the BIM environment. The development of methods to help the incorporation of already existing environments within BIM will be of great value within FM, building conservation and new design alike. Therefore, the refinement and adoption of clear methods to support such work is a vital step towards BIM maturation.
